CISSP stands for Certified Information Systems Security Professionals who work for the security of computer system and stop data theft. In fact computer security became a key question in last years of 1980s and requirement for data protection and network security became a primary concern. CISSP professionals work for protection of information from theft, corruption, natural disaster, etc. Additionally, along with protecting the precious data from unauthorized users, CISSP professionals are expected to enable authorized users have access to all the data or system. A concern which was local at the beginning became a global issue and in 1980s computer companies started to put consorted efforts towards standardization of the entire computer protection system.

Came November 1988 when the Special Interest Group for Computer Security (SIG-CS) which was an allied force of the Data Processing Management Association (DPMA) with the help of several other entities from around the world focused on the issue and formed the International Information Systems Security Certification Consortium (ISC). The ISC holds CISSP exams to offer membership to professionals who clear it. Over the time CISSP certification exam has become one of the popular one and candidates from various parts of the world participate to become one of the certified CISSP professional. CISSP certification not only helps candidates get recognition but gives edge to qualifications held by the candidate. Similarly, with due course of time a number of training organizations have come up which claim to train candidates clear CISSP certification exam.

In order to clear CISSP exam a candidate must read and solve previous years’ CISSP exam questions so that familiarity with the genre of question is made possible.
Interestingly, the CISSP certification is valid for only three years. Therefore, after three years, the candidate has to appear for exam and clear it to become a CISSP. However, the re-examination can be avoided if the candidate undergoes 120 Continuing Professional Education (CPE) credits program which is conducted by the organization. With earning and submission of 120 CPEs, an existing member of CISSP can continue his membership even after three years of completion of the membership. The member is asked to pay an annual fee of US$ 85 during each year of the three-year certification cycle before the annual anniversary date.
